Everyone has an opinion as to what is the seed favored at feeders. Based on my experiences, I believe sunflowers seeds are favored by the most seed-eating feeder birds in Georgia. Some 40 species including cardinals, tufted titmice, Carolina chickadees, brown-headed and white-breasted nuthatches, house and purple finches are some of the birds that dine on sunflower seeds.
If you decide to purchase sunflower seeds, I recommend you purchase black-oil sunflower seeds. Black oil sunflower seeds have thinner shells, which permits birds to open them more easily. In addition, their kernels contain more fat and calories than striped sunflower seeds.
